I'm not exactly understanding what you're trying to do, but here are a couple of things to keep in mind:

- functions need to be embedded in the SELECT clause, not the WHERE clause.

- I have found that most MySQL interfaces require dates to be quotes; e.g., WHERE date = '2013'.

So a query like this should be legal (not tested):

SELECT foo, bar, MIN(date) FROM myTable WHERE date < '2012'

Again, I don't understand exactly what you want, but this might give you some clues.
